The object of this invention is to provide novel means for connecting the walklng beam of a pumping apparatus with the polish rod of a deep well pump whereby the polish rod will be kept to a rectilinear path, and lateral-movement of the same in the stuifing box of the tubing, and consequent wear upon the stufling box and the polish rod, will be eliminated. Theinvention also has for its object the provision of means whereby the ban er may be adjusted to the stroke of the wal ing beam or to the length of the same, and other incidental objects will appear in the course of the following de- 1 scription. The invention resides in certain novel features which will be particularly pointed out in the appended claims.

In the accompanying drawings which illustrate apparatus embodying the invention:

Fig. 8 is a detail sectional elevation showing a modification, and

Fig. 9 is a diagrammatic view illustrating the positions assumed by the parts of the hanger during the working stroke of the walking beam.

The walking beam is indicated at 1 and is preferably a metal I-beam, but it may be of woodif desired. The beam is fulcrumed, as indicated at 2, on the upper end of a standard 3, and its forward working end is beveled, as shown at 4, being forked or slotted, as indicated at 5, and having-the back wall of the slot inclined downwardly and rearwardly, as indicated by the dotted line in Fig. 1.

The hanger comprises an upper member or main body 6 which has its upper end tapered or reduced relative to its lower end so that it may extend through and work freel in the slot or notch 5 inthe end of the wal 'ng beam, and at its upper extremity said member is provided with an eye 7 in which a hoist may be engaged in order to raise or lower the hanger and the pumping elements when it is to be assembled with or removed from the walking beam. The upper main member 6 is formed with a bend or offset,

shown'at 8, near its upper end and above said bend has an opening 9 the'rethrough which receives the fulcrum pin or pivotal support 10 consisting of a pin or rod of circular cross section provided at its center on its upper side with a knob or arcuate pro: jection which is adapted to fit in a socket 12 formed in the top wall of the opening 9. After the fulcrum pin has been fitted in place, a plate 72 is disposed in the opening 9 below and in contact with the under side of the pin and is welded to the bottom of the opening, thereby preventing removal and loss of the pin, when raising the hanger into place or removin it from the walking beam. B reason of t 's arrangement, the hanger w' assume a vertical pendent position, notwith-- standing that the upper side of the walking beam may possibly be not truly horizontal transversely of the beam, the supporting element following the angularity or inclination of the top surface of the beam, and the ball and socket engagement of the pin and hanger permitting the hanger to .remain in an 11 right position without any cramping or bin ing upon the support. The body 6 is provided at its lower end with a rearward extension 13 through which is formed anarcu ate slot 14, the major axis of which is substantially at a right angle to the axis of the body, and above its lower end the body 6 is provided with a transverse opening to receive a rod or shaft 15, the body being longitudinally slitted, as shown at 16, above and below said openin whereby the shaft or rod 15 may be firmly c amped by bolts 17 inserted through the body at 1'1 ht angles to the slits or kerfs, as will be un erstood. The slot 14 109 receivesa transverse shaft or rod 18 which ment of this rod or shaft 18, an abutment 19 e is provided within the rear ortion of the slot and is, adjustable longitudinally of the slot by means of a set bolt 20 which is-threaded through the rear wall of the slot and has its forward end swiveled in the abutment, a lock nut 21 being mounted on this set bolt to bear against the rear end of the extension 13 and thereby lock the bolt in a set position, as will be understood. On the rear side of the body 6 near the lower end thereof is a lug 22 having an o ning 23 therethrough, the purpose of whic will presently appear.

Disposed at opposite sides of the upper main body 6 of the hanger are intermediate members or links 24 which are formed with eyes 25 at their upper ends to fit around the ends of the shaft or'rod 15, the eyes being lined with bushings 26, as will be understood. The eyes 25 fit pivotally upon the ends of the rod 15 so that the links 24 may swingrelatively to the body 6, and oil cups 27 are provided in the upper sides ofthe eyes 25 to supply lubricant to the bearings. The eyes 25 are held against slipping from the rod 15 in any convenient manner, washers or 'cap plates 28 being shown in Fig. 2, held in position by screws 29 fitted therethrough and engaged in sockets in the ends of the rod, as will be understood. The lower ends of the links 24 are split, as indicated at 30, and the upper portion of each split is enlarged and given a circular formation, as shown at 31, whereby it may receive the shaft 18, a bolt 32 being fitted through the lugs 33 at the lower end of the split whereby the shaft or rod 18 may be firmly clamped in the lower ends of the links. Each link is furthermore provided with a rearward extension 34 which is disposed close against the sides of the extension 13 of the main body 6 and is of like contour, whereby it will serve as a guard to prevent an accumulation of dirt and other foreign matter within the slot 14 to interfere with the proper movement of the parts.

The rod or shaft 18 is of such length that its ends project laterally beyond the sides of the links 24, as will be understood upon reference to Fig. 2, and upon the ends of.

said rod or shaft are mounted the lower members or links 35, the upper portions of said links being substantially cylindrical'bodies or eyes 36 which are pivotally engaged with the shaft or rod 18 and are provided with bushings 37 to minimize wear. The lower portions of the links are in the form of forks 38, having openings 39 formed trans- The eyes or cylindrical portions of the links are equipped with oil cups 40 to supply lubricant to the bearings. The reins 41 have their ,device. versely therethrough near their lower ends.

upper ends of the reins and the openin s 39' in the links, as will be understood, an the lower ends of the reins are pivotally attached to the polishrod'or to a coupling, indicated at 43, which is in turn secured to the upper v end of the polish rod.

At the under side of the walking beam adjacent the front end of the same are mounted supporting blocks or brackets 44 which, as shown most clearly in Fig. 7 have depending portions, at the upper ends of which are laterally ofi'set heads 45, and these ofl'set portions are each undercut on their inner faces at their upper extremities to provide overhanging flanges 46 adapted to engage over the lower flanges of the walking beam, as shown in Fig. 7, and they are also formed into teeth 47, as shown most clearly in Fig. 6, whereby they may be firmly engaged with the sides of a wooden beam. Through the depending portions or flanges of these clamping plates I pr blocks 44 are inserted bolts 48 and 49, the bolt 48 being located near the rear ends of the blocks or brackets and of such len h that it may extend through the depending flanges of both brackets, while the bolts 49 are shorter and are enga ed at their inner ends with the depending anges or branches of an inverted U-shaped plate or block 50 which is disposed between the depending portions of-the blocks 44, as clearly shown in Figs. 6 and 7. The inverted U-shaped block or bracket 50 is formed at its front end with a central forwardly projecting lug 51 having a central opening therethrough, as shown. In assembling the parts, the bolt 48 is tightened just enough to hold the clamp blocks 44 against dropping, and the block 50 is thereupon brought into position midway between the clamp blocks 44. The boltsr49 are inserted through the depending portions of the blocks 44 and the depending branches of the block 50, and the nuts thereon thenturned home, proper adjustment of the block 50 being effected by setting the several securing nuts in an obvious manner. A kick-ofi' device extends between the lug 51 and the lug 22 of the main body 6 and consists of a tubular member 52 having a forked rear end 53 spanning and pivotally attached to the lug 51, anda threaded rod or bolt 54 having a fork 55 at its front end which spans and is pivotally attached to the lug 22', the rod 54 fitting within the tube 52, as shown in Fig. 1. Adjusting and lock nuts 56 are mounted upon the member 54 and bear against the open end of the tubular member 52 to properly adjust and secure the telescopic kick-01f Generally, the kick-off device will be pivoted directly to the lug 51, as has been described and as is shown in Fig. 1, but it may be desired at times to have the thrust of the kick-oil device received by the back wall of the slot in the walking beam, and the link 57 may then be employed. This link hasone end pivoted to the lug 51 and its other end 5 pivoted to the rear end of the tubular member 52, as clearly shown in Fig. 8, the latter end extending u wardly within the slot or notch 5 in the en of the beam and being beveled to bear squarely against the back wall of the slot. v m The hanger is adjusted when the walking beam is at the lower end of its stroke, that is, the position indicated at the bottom of Fig. 9. The bend 8 in the upper or main body 6 of the hanger is so located that when the parts are properly adjusted and the walking beam is at the lower end of its stroke, the several rods or shafts 10, 15 and 18 will be in vertical alinement, and the reins and 0 polish rod will be axially alined with the pivots 42, the rod or shaft 18 at this time resting at the front end of the slot 14. As the walking beam swings upwardly, the pm or supporting rod 10 will move relatively 1nward, due to the arcuate path it follows, it

being noted upon reference to Fig. 9 that in the lowest position of the parts the fulcrum 2 and the pivot 10 are in the same horizontal plane. The kick-oil device, however, being lower than the fulcrum 2 at its pointof attachment to the upper main member 6 of the hanger, will be pushing the lower end of said member outwardly .or forwardly at its lower end so that it will rock with the shaft 15, and the rod or shaft 18 will assume a position approaching the rear end of the slot 14, the links 24 and 35 remaining in a vertical plane. This relation of the parts wll continue through the full stroke of the beam so that the rod or shaft 18, from which the links 35 are suspended, will remain vertically over the polish rod. When the relative movement of the members 6 and 24 has brought the rod or shaft 18 into engagement with the abutment 19, the continued upward movement of the walking beam, and the ensuing forward rocking of-the lower end of the member 6, will act upon the said member 18 soas to push the same forwardly or outwardly and thus maintain it directly over the center of the well tubing. The adjustment of the kickoff device and the adjustment of the abutment 19 permits the apparatus to be set so as to conformto the stroke or length of the walking beam, and the device will operate easily and efiiciently at all times.
